I wouldn't worry too much. They three of them are 22, 20 & 21 years of age, respectively. Very young for defensemen.
I did some research on Defensemen this weekend for the last two blog posts, and here's who I looked at: Zanon, Hejda, O'Byrne, Colaiacovo, Garrison, & Carle. Of that group only Carle got any regular NHL time before the age of 25.
Just a reminder that if those guys stay in LE the next few seasons, they aren't busts or anything. It's pretty common for defensemen to need some seasoning.
